The best place to dispose of spent coffee pucks is a knock chute.
Knock chutes are inserted into the counter - the waste is collected in a bag under the counter.– simply bang the portafilter firmly on the knock bar, and the dry puck will fall into the knock box and be disposed of into the compost heap.
Use the Coffee Knock Drawer Co. Coffee Knock Chuteto reduce Barista arm fatigue and reduce workplace injury.
